DETAILED DESCRIPTION

The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.

One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details.

A solid-state microbattery can comprise a solid-state electrolyte rather than a liquid electrolyte to allow an electrical charge to flow between an anode terminal and a cathode terminal of the solid-state microbattery. With recent advances in electronic technologies, solid-state microbatteries are becoming more common in electronic devices. However, batch processing and/or packaging of a large quantity of solid-state microbatteries to facilitate fabrication of solid-state microbatteries is often difficult and/or time consuming. Furthermore, singulation of solid-state microbatteries often leads to edge defects that allow air leaks in the solid-state batteries. Testing of numerous solid-state microbatteries is also difficult during fabrication, batch processing and/or packaging of the solid-state batteries.

Embodiments described herein include systems, methods, apparatuses and devices that facilitate improved packaging and/or testing of solid-state batteries. For example, novel solid-state microbattery packaging and/or novel solid-state microbattery testing can be provided. In an embodiment, a releasable adhesive material can be employed to provide improved handling, testing, singulation and/or packaging of solid-state batteries. In another embodiment, an overmold comprised of a polymer sealing material can be applied to seal packaging of solid-state batteries. In yet another embodiment, a tool can be employed to form an array of solid-state microbatteries that satisfy a defined criterion (e.g., an array of solid-state microbatteries that are determined to be functioning properly) on a releasable adhesive material. Additionally or alternatively, a releasable adhesive material can be employed to provide stacking of two or more solid-state batteries. In yet another embodiment, a releasable adhesive material can be employed to temporarily hold a set of cap wafers for a set of solid-state microbatteries to provide stress free bonding and/or sealing of the set of solid-state batteries. In yet another embodiment, a set of solid-state microbattery components are formed on a surface of a handler substrate layer. The handler substrate layer can be a tape or a glass with a releasable adhesive material. A conductive surface associated with the set of solid-state microbattery components can be disposed on the releasable adhesive material of the handler substrate layer. As such, solid-state microbattery packaging with a molding structure for hermetic or near hermetic packaging around a solid-state microbattery can be provided. Moreover, impact of laser cutting to an adhesive bond interface of solid-state microbattery packaging can be reduced in order to provide an air tight seal for the solid-state microbattery packaging. A batch process can also be improved by employing a releasable adhesive material to enable mass production of solid-state microbattery packaging. Furthermore, a releasable adhesive material can provide an ability to test numerous solid-state microbatteries in parallel. Protection of solid-state microbatteries within solid-state microbattery packaging and/or improved quality of solid-state microbatteries within solid-state microbattery packaging can also be provided.

FIG. 1 illustrates a block diagram of an example, non-limiting system 100 that facilitates improved solid-state microbattery packaging in accordance with one or more embodiments described herein. In various embodiments, the system 100 can be a solid-state microbattery packaging system. For example, the system 100 can be a thin film solid-state microbattery packaging system. The system 100 can employ a novel device (e.g., novel solid-state microbattery packaging and/or a novel solid-state microbattery device) that is highly technical in nature, that is not abstract and that cannot be created by a set of mental acts by a human. Further, the system 100 can be employed to solve new problems that arise through advancements in technology such as, for example, solid-state microbattery technologies, solid-state microbattery packaging technologies, circuit technologies, and/or computer architecture, and the like. One or more embodiments of the system 100 can provide technical improvements to a solid-state microbattery device by at least improving quality of a solid-state microbattery, improving adhesive sealing for a solid-state microbattery, providing a molding structure for hermetic or near hermetic packaging for one or more solid-state batteries, providing air tight sealing for one or more solid-state batteries, eliminating impact of laser cutting to an adhesive bond interface for one or more solid-state batteries, providing a batch process that enables mass production of solid-state batteries, and/or providing improved testing of numerous solid-state microbatteries in parallel.

In the embodiment shown in FIG. 1, the system 100 can include a solid-state microbattery component 104 a, a solid-state microbattery component 104 b, a substrate layer 106, a releasable handler layer 108, a cap wafer 107 a, a cap wafer 107 b, polymer sealing material 110 a, and polymer sealing material 110 b. In one example, the releasable handler layer 108, the polymer sealing material 110 a and/or the polymer sealing material 110 b can form an adhesive layer. The solid-state microbattery component 104 a can include, for example, an anode, a cathode and/or a solid-state electrolyte that form a solid-state microbattery. Similarly, the solid-state microbattery component 104 b can include, for example, an anode, a cathode and/or a solid-state electrolyte that form a solid-state microbattery. In one example, the solid-state microbattery component 104 a and/or the solid-state microbattery component 104 b can be a solid-state lithium microbattery component (e.g., a thin film solid-state lithium microbattery component). However, it is to be appreciated that the solid-state microbattery component 104 a and/or the solid-state microbattery component 104 b can be a different type of solid-state microbattery component. The substrate layer 106 can be, for example, a handler substrate layer that comprises an insulator material, a glass material or a silicon material. The releasable handler layer 108 can be, for example, an adhesive layer that is releasable from the cap wafer 107 a and/or the cap wafer 107 b. The polymer sealing material 110 a can be, for example, a polymer adhesive that facilitates bonding between the cap wafer 107 a and the substrate layer 106. For example, the polymer sealing material 110 a can be a synthetic bonding substance comprised of polymers. The polymer sealing material 110 a can also create an air-tight seal for the solid-state microbattery component 104 a. For instance, the polymer sealing material 110 a can be an overmold comprised of a polymer adhesive to facilitate sealing of the solid-state microbattery component 104 a from an external environment (e.g., air surrounding solid-state microbattery packaging associated with the solid-state microbattery component 104 a). Similarly, the polymer sealing material 110 b can be, for example, a polymer adhesive that facilitates bonding between the cap wafer 107 b and the substrate layer 106. For example, the polymer sealing material 110 a can be a synthetic bonding substance comprised of polymers. The polymer sealing material 110 b can also create an air-tight seal for the solid-state microbattery component 104 b. For instance, the polymer sealing material 110 b can be an overmold comprised of a polymer adhesive to facilitate sealing of the solid-state microbattery component 104 b from an external environment (e.g., air surrounding solid-state microbattery packaging associated with the solid-state microbattery component 104 b).

In an embodiment, the solid-state microbattery component 104 a and the solid-state microbattery component 104 b can be formed on the substrate layer 106. For example, a conductive surface of the solid-state microbattery component 104 a and a conductive surface of the solid-state microbattery component 104 b can be in contact with the substrate layer 106. Furthermore, the cap wafer 107 a can be formed on the solid-state microbattery component 104 a. The cap wafer 107 a can be, for example, an insulator cap layer. The cap wafer 107 a can be aligned and bonded onto the solid-state microbattery component 104 a using the releasable handler layer 108 and/or the polymer sealing material 110 a. In an aspect, the polymer sealing material 110 a can be in contact with the solid-state microbattery component 104 a, the substrate layer 106 and the cap wafer 107 a. The solid-state microbattery component 104 a can also be disposed within the polymer sealing material 110 a. For instance, a first surface of the solid-state microbattery component 104 a can be in contact with the substrate layer 106, a second surface of the solid-state microbattery component 104 a can be in contact with the cap wafer 107 a, a third surface of the solid-state microbattery component 104 a can be in contact with the polymer sealing material 110 a, and a fourth surface of the solid-state microbattery component 104 a can be in contact with the polymer sealing material 110 a. Similarly, the cap wafer 107 b can be formed on the solid-state microbattery component 104 b. The cap wafer 107 b can be, for example, an insulator cap layer. The cap wafer 107 b can be aligned and bonded onto the solid-state microbattery component 104 b using the releasable handler layer 108 and/or the polymer sealing material 110 b. In an aspect, the polymer sealing material 110 b can be in contact with the solid-state microbattery component 104 b, the substrate layer 106 and the cap wafer 107 b. The solid-state microbattery component 104 b can also be disposed within the polymer sealing material 110 b. For instance, a first surface of the solid-state microbattery component 104 b can be in contact with the substrate layer 106, a second surface of the solid-state microbattery component 104 b can be in contact with the cap wafer 107 b, a third surface of the solid-state microbattery component 104 b can be in contact with the polymer sealing material 110 b, and a fourth surface of the solid-state microbattery component 104 b can be in contact with the polymer sealing material 110 b. As such, the solid-state microbattery component 104 a can be associated with a first portion of the polymer sealing material 110 a that is separate from a second portion of the polymer sealing material 110 b associated with the solid-state microbattery component 104 b. It is to be appreciated that, in certain embodiments, the system 100 can include more than two solid-state microbattery component (e.g., one or more additional solid-state microbattery component than the solid-state microbattery component 104 a and the solid-state microbattery component 104 b).

The releasable handler layer 108 can be, for example, a handler substrate layer (e.g., an adhesive substrate layer, a tape substrate layer, etc.). The releasable handler layer 108 can be attached to the cap wafer 107 a and the cap wafer 107 b. Furthermore, the releasable handler layer 108 can be configured to be removable from the cap wafer 107 a and the cap wafer 107 b. In one example, the releasable handler layer 108 can comprise a pressure-sensitive tape. In another example, the releasable handler layer 108 be a dicing tape that comprises polyvinyl chloride, polyolefin, polyethylene or another adhesive material. However, it is to be appreciated that the releasable handler layer 108 can comprise a different type of releasable adhesive material. In an aspect, the releasable handler layer 108 can be a handler layer to facilitate handling of the cap wafer 107 a, the cap wafer 107 b, the polymer sealing material 110 a and/or the polymer sealing material 110 b. As such, the releasable handler layer 108 can facilitate improved batch transfer and/or bonding of the cap wafer 107 a and the cap wafer 107 b onto the solid-state microbattery component 104 a and the solid-state microbattery component 104 b. Furthermore, the releasable handler layer 108 can facilitate improved sealing for the solid-state microbattery component 104 a and the solid-state microbattery component 104 b. Furthermore, the releasable handler layer 108 can facilitate improved protection of the solid-state microbattery component 104 a and the solid-state microbattery component 104 b during a shipping process. In certain embodiments, the releasable handler layer 108 can be employed to stack two or more solid-state microbattery components. For example, the releasable handler layer 108 can be employed to stack the solid-state microbattery component 104 a and the solid-state microbattery component 104 b to form a stacked solid-state microbattery packaging. In one example, the solid-state microbattery component 104 a and the solid-state microbattery component 104 b can be stacked in a serial configuration using the releasable handler layer 108 to provide higher voltage capabilities. In another example, the solid-state microbattery component 104 a and the solid-state microbattery component 104 b can be stacked in a parallel configuration using the releasable handler layer 108 to provide higher capacity capabilities. In certain embodiments, a laser release process can separate the solid-state microbattery component 104 a and the solid-state microbattery component 104 b by cutting through the substrate layer 106 and/or the releasable handler layer 108 using a laser beam.

In an embodiment, a laser release process 402 can be performed to remove a solid-state microbattery component 104 a-h (e.g., solid-state microbattery component 104) from the substrate layer 106. For instance, a portion 404 of the substrate layer 106 can be cut through via the laser release process 402 to facilitate removal of a solid-state microbattery component 104 a-h (e.g., solid-state microbattery component 104) from the substrate layer 106. In certain embodiments, the releasable handler layer 108 and/or a releasable adhesive material can be employed to facilitate removal of a solid-state microbattery component (e.g., solid-state microbattery component 104 a) from the substrate layer 106. For example, the solid-state microbattery components 104 a-h can be disposed on a first surface of the substrate layer 106. Furthermore, the releasable handler layer 108 can be disposed on a second surface of the substrate layer 106.

For example, a solid-state microbattery component 504 a from the solid-state microbattery components 504 can be added to a releasable handler layer or a substrate layer. Alternatively, the solid-state microbattery component 504 a from the solid-state microbattery components 504 can be removed from the surface 502. For example, the solid-state microbattery component 504 a from the solid-state microbattery components 504 can be removed from a releasable handler layer or a substrate layer.
